Woezor! (welcome)
Learning something new can bring up wonder, curiosity and the desire for accomplishment. We do not have a vast library of what should educate you end-to-end about open source projects, but have grouped some resources to guide you to understanding the key things. It is encouraged for beginners to take the link resources one at a time to grasp its meaning.
I hear a lot of Pull Requests around Github
Technical Stuff! But I don't understand coding
In as much as we encourage you to feel free to broaden your reading or research about open source, we also want to emphasis greater learning by practicing. The world awaits your impact, you can always start small. Wishing you good luck with us all the way.
